I don't know how old your system is but the battery packs have lifetimes that seem to vary from about 6 months to a couple of years.
I'm curious as to how you have established that the battery is getting 'full charge?'
The three keyboard LEDs are the start of the 'power-on self-check' and the fact that they go out again can mean that they are finished with the keyboard test and that the initialization is proceeding or that the battery voltage has collapsed.
If you don't own a multimeter (you should-they are cheap) I don't know how you know whether the battery pack is charged or not.
Battery packs can also fail without dying of old age; there is a thermal fuse in all of them that will melt open if the temperature surpasses a safe point (fairly low) and these Chinese parts are terribly unreliable and may fail just for fun. When this happens, they will not charge and in some, they won't produce any voltage at the pack's contacts either.

Thanks for the help. It looks like the battiers have fully charged because the small green light on the charger is steady green and that means the batterys are charged. I put a volt meter on the batterys...

Phil after a full charge you should be reading more than 24.8 volts on the batteries I'm still leaning toward replacing the batteries of course thats not cheap but if you can locate 2 batteries from a provider that will let you try them on the scooter to see if that fixes the flashes you are getting I don't have too many more ideas to give you sorry

Not charging. the wheelchair has a short in the wiring. so I suspect that the wheelchair doesn't charge due the short. possible?

If there is a short there will be flashing lights. If the lights don't come on at all, check all of the connections and fuses. If that all checks OK but the Power chair will not come on, It sounds like the batteries have gone bad and need to be replaced.

The batteries contain a gel that needs to have current run through it on a regular basis (at least 8 hours once a week) or it will solidify. If you attach the charger, what will most likely happen is the green light will either stay green or go to green after a very short time. When you turn on the power chair, nothing happens. The charger will indicate the batteries are full, but instead of being full of pwer, they are full of crud. Your warranty will most likely not cover replacment as this is due to customer neglect, but your insurance may still cover the replacement if you can wait for the process to go through. Otherwise, you will need to replace the batteries on your own. Good luck!

Randal the problem sounds like a battery issue. If after charging you get a green light on the charger and the batteries run down quickly there is one or both of the batteries that is weak and cannot handle the load required by the motors. If Medicare paid for your chair contact the provider that sold you your chair and ask them to come replace the batteries. They should then bill Medicare for the batteries. Hope this helps

Battery is fully charged but when I turn ignition key nothing happens, on light does'nt come on and needle does'nt move battery level

Has the scooter been sitting unused for a while? If so, the gel inside the rechargeable batteries may have gone solid. When you connect the charger, the light shows green indicating the batteries are full, but instead of being full of power, they are full of crud. The scooter can sit for just a few weeks and this will happen. If the batteries are new or have been properly maintained, try checking your fuses and all the connections/leads as this certainly sounds like a power problem.
Good luck!

The battery wont stay charged .when you plug it in to charge the green light comes on ,when fully charged the red light is on,when you turn it on no power

If the charger is automatically giving you a green light when you plug in the charger, the batteries are most likely damaged and will no longer take a charge. This can happen when the power chair is stored and the batteries are not charged for a while. The green light on the charger indicates the battery is full, but instead of being full of power, its full of crud. Try to replace the batteries and see if that will solve the problem.

When connecting up to charge red light comes on 'power on' button on front and no charging happens - any ideas? thanks

What does indicator light mean?
  • Steady red light: Battery is charging.
  • Steady green light: Battery is fully charged.
  • Flashing red light: Battery needs charging.
  • Flashing green light: The music receiver is switched on.
  • Flashing red/green light: The music receiver is available to be added to your phone.

My iRobot scooba won't turn on after a full charge

Do you have the charger terminal, or do you have the charger that you have to take out the battery and charge. Because I have found that my base terminal charger works better than the battery charger that needs the battery to be removed to charge.If you have the terminal charger and the power light is green when it is in the charger I would start from the terminal

Mac Ibook Power supply problem

On Mac iBooks the orange light comes on when it charges the battery. Once the battery is charged it turns green. Im guessing the other powersupply was aftermarket or broken. EIther way, if it starts out green - recognizes the battery isnt full - turns orange for a while - then turns green when the battery is full, then the computer and powersupply are working perfectly. Enjoy your iBook!
